Do yourself and your friends a big favor and stay at Encore or Wynn. Pre-pay the night's cover charge ($30 - $50 per guy; less for girls) at the concierge desk the day that you want to go and you will receive your "golden tickets" right there and then. Show the bouncers your tickets and you will enter the club without any questions or fuss. I went with four of my guy friends and it was just too easy to get in. Ratio? What ratio? The "golden tickets" just told the bouncers to shut up and let us in. And they obliged. Haha!
